Abstract

Preparation of nitriles by hydrocyanation of olefins in the presence of a ruthenium catalyst. Comprises contacting the 2 - 20 C olefins at -25 to 200 degrees C with hydrogen cyanide in the presence of a ruthenium catalyst of formula (M1Z3)n RuXm (in which n is 2 to 4, the sum of n + m is 4 or 5, X is a halide or cyanide, Z is alkyl, alkoxy, aryl or aryloxy having up to 18C atoms and M1 is P, As or Sb). Used as chemical intermediates, e.g. for the preparation of nylon. The process has the advantage that nitriles are prepd. in high yield, under mild conditions, with minimal formation of polymer.
